Could 的用法
1.could为can 的过去式，表示过去的能力。可以与 be able to 转换。
Could you play the piano when you were at the age of 4.
2. Could you please +动词原形+其它
一种表示请求或征询对方意见的客气委婉的说法，
could 在此句型里表示请求，而不是can的过去式，could 比 can 的语气更加委婉、客气，让人易于接受.因此平日里人们更多使用could,而不用can. 否定句直接在please后加not
eg. Could you please take out the trash
Could you please not tell him about it
